Patented July 4, 1939 UNITED STATES PATENT OFFlCE 1 Claim.

My invention refers to adjusters or stops to selectively limit the mov-ement of swinging doors,

the same being particularly adapted for use in.

connection with garage doors, whereby the same 5 are held against swinging movement either in open, closed, or intermediate positions.

It is a well-known fact that garage doors in particular are difficult to lock in their various adjusted positions against swinging, due to wind pressures and the weight of said doors, and when such doors are inadvertently swung in or out, they frequently seriously damage an automobile entering the same, often resulting, also, in breaking the Windows in the doors. I have had conl5 siderable experience in this line and have found the usual methods of locking doors in predetermined positions frequently result in failure. My present garage door-holder invention is a simpliiication of the structure disclosed in my prior Patent No. 2,080,097, issued to me on May 11, 1937.

An important object of my invention is to provide a simple plate and strap in slidable union in conjunction with a link, whereby relative movement is imparted to the strap incidental to swinging movement of a door, these parts being locked by friction mechanism.

Specific objects of my invention are to provide a channeled plate adapted to be secured to a door; a longitudinally slotted strap slidable with relation to the plate; a stud carried by the plate having friction means for locking said plate and strap together; and a toggle link carried by the strap in hinged connection with a fixed point with relation to the door hinges.

With the above and other minor objects in view the invention consists in certain peculiarities of construction and combination of parts, as will be hereinafter set forth with reference to the claim.

In the drawing:

Figure 1 represents a face View of a swinging. door control mechanism, with parts broken away and in section to more clearly illustrate structural features, a fragment of the door and its frame being shown as associated with the device.

Figure 2 is a cross section of the same, the section being indicated by the line 2 2 of Figure 1, said View being shown with a swinging door partly open.

Figure 3 is a magnified cross section of the door adjuster mechanism, the section being indicated by line 3-3 of Figure 1.

Figure 4 is a similar cross sectional view upon another plane, as indicated by line 4-4 of Figure 1; and v Figure 5 is a detailed cross section indicated by line 5 5 of Figure 1, said cross section showing a sliding guide in conjunction with the associated parts.

Referring by characters to the drawing, A in- 5 dicates a swinging door hinged at B to a casing or frame C, all of which parts are of standard construction. Secured by screws to the inner face of the door is a plate l, having ears extending from the top and bottom edges for reception 10 of said screw. The remaining portion of the edges of the plate l are formed with inturned anges 2, which constitute edged channels for the reception of a strap 3, which is slidable therev in. The strap 3 is provided with a longitudinal 15 slot 4, through which slot a threaded stud 5 eX- tends. 'Ihe stud 5 is secured to the plate l by a block 5', which is embedded in a seat that is provided therefor in said plate. A friction washer 6 is mounted upon the stud engageable with 20 the surface of the sliding strap 3. The friction washer in turn is frictionally engaged by the inner or nut portion of a lever 1.

In order to prevent rotation of the stud 5, its threaded end is flattened for the reception of a 25 Spanner guide 8, the ends of which, as best shown in Figure 5, extend through the slot of the strap 3. The Spanner guide is in turn held in position by a cap nut 9, which is threaded upon the iiattened end of the stud. 3o

The inner end of the sliding strap 3 terminates with a hinge and pintle element 3', which has loosely mounted therein one end of a link I0. The link, as shown in Figure 2, is offset, and its opposite end is in pivotal union with a bracket 35 Il, the said bracket being secured to a convenient portion of the xed door frame and upon the inner side of said door.

From the foregoing description, it is manifest that when the door is swung to a full open or 40 closed position, or an intermediate position, a sliding movement takes place with relation to the strap 3 and the plate I. Hence, When the door is in the desired position, it can be positively locked in such position by a simple manual swing- 45 ing action of the nut lever 1, whereby the associated parts of the plate and strap are tightly bound together by the friction elements. This action, with relation to the parts, is due to the fact that the fixed pintle of the toggle link is 50 offset with relation to the axis of the door hinges, as shown, in Figure 2 of the drawing.

It will also be noted that when the adjuster device is upon the inner face of the door, it can be manipulated tO adjust the door from the in- 55 side, whereby said door cannot be tampered With from the outside. In other Words, the device serves as a positive door bolt under such conditions.

While I have mentioned that the invention is applicable to doors, it is quite suitable for swinging Windows, or the like.

While I have shown and described specically one exemplication of my invention minutely as to all details, it is understood that I may vary the structural features within the scope of the claim.

I claim:

An adjuster for swinging doors comprising, a plate adapted to be secured to a door having ilanges on its edges forming channels, a threaded stud 'carried by the plate and held against movement thereon, a slotted strap guided in the plate channels and normally movable longitudinally of the plate, the stud extending through the slot in the strap, a friction member slidably mounted upon the stud movable toward and away from the strap for frictional Contact therewith, a lever threaded upon the stud, whereby upon movement of the lever in one direction for threading the same upon the stud, the friction member will engage said strap and hold the strap tight against said plate, a link pivotally secured to the strap and adapted to be pivotally connected to the door frame, a U-shaped bracket mounted upon the stud against swinging movement and having its terminals extending through the slot in the strap, whereby the stud, strap, and U-shaped bracket will be held against relative turning movement, and means holding the U-shaped bracket against displacement off the stud.
